NASTRAN计算磁盘空间不足问题?
请那位兄弟帮忙分析一下,是模型的问题还是机器设置的问题,不胜感激!本次计算模型自由度为1194788,nastran界面提示需要内存171.5MB,磁盘11033.4MB。
计算盘里有30多G的空间。我已将SCRATCH文件移到计算盘目录F:下。F06文件提示磁盘空间不足,详细错误如下:

回复 楼主 的帖子
增大虚拟内存;或者检查你硬盘的文件格式是否是NTFS 感谢楼主解答,我会试试!我原来计算用的是新配的机器出现问题,后来我又用原来的老机器算了一下,老机器内存1G,磁盘也小了不少反而能算了,不过计算时间长了很多。 把你的fatal message 百度一下,就可以看到解决办法,求解时:direct text input-》file management section中输入:
nastran system(151)=1
nastran system(1)=32769
在nastran求解控制中,输入scr=yes,选择不生成dball文件,节省磁盘空间。 感谢各位朋友的指点!将磁盘格式由FAT32改为NTFS后可以计算了 hanfeifei 发表于 2008-7-15 09:24 static/image/common/back.gif

这两句话是什么意思
